MINE CAR.

Application led May 15, 1925. Serial No. 30,540.

- In the drawings:

Fig. 1 is a side elevation of a mine car constructed in accordance with this invention, parts being broken away at one end in order to show an end of the drawbar, a coupling member and a bumper more clearly Fig. -2 is a transverse section of the car shown in Fig. 1 taken on the line 2-2 of Fig. 3;

Fig. 3 is a top plan view of the mine car shown in Fig. 1; and

Fig. 4 is a partial front elevation of the end gate.

This invention relates to mine cars and has as an object t'o provide an improved mine car of composite construction having side sills connected together to form a rigid frame for the car. It is also an object to provide an improved means for bracing the side sills and side floor portions of the car. It is also an object to provide an improved lfirking means for a car of the type speci- With these and othervobjects in view, a mine car constructed in accordance with this invention comprises, as shown in the drawings, Z-shape side sills 2 having the webs 3 vertical, the, top flanges 4 projecting outwardly and the bottom flanges 5 projecting inwardly. While the side sills are shown as formed of pressed members, it is to be understood that they ma be formed of suitable rolled shapes. To t e side sills 2 are secured journal boxes 7 in which are mounted the axles 9 carrying wheels 10, the journal boxes having their tops shaped to receive the side sills and having flanges bolted to the flanges of the sills. To the upper flanges 4 of the side sills 2 are secured metal sheets 12 which form the otwarlly projecting side floor portions 14 and are bent upwardly to form the sides 15 of the car, the upper edges ofthe sides being turned over inwardly to form reenforced upper edges 16.

At the ends of the car and adjacent to the .wheels 10, strap braces 18, which extend from the edge 16 of one side to the edge 16 of the other side, are secured to the sides and side licor portions and to the bottom flanges A5 of the side sills 2. v

At the center of the car, a channel-shape tie member 2O having laterally projecting fian es 22 extends from one side to the other of t e car, its anges 22 being fastened to the bottom flanges 5 of the side sills 2 and its ends bent upwardly so that the flanges 22 contact with the side floor portions 14 of the sheets 12 and to which the flanges 22'are riveted. At each end of the tie braces 23 are secured to the sides 15 of the'car and to the webs 24 of the ties 20.

Mounted on the braces 18 and tie 20 and extending longitudinally of the car at its center Vis an inverted U-shape drawbar or buffer beam 26 having outwardly projecting flanges 27 which are riveted to the braces 18 and the flanges 22 of the tie 20. Between the drawbar 26 and the side sills 2 are planks cured bumpers 32 having top plates 34 which.

rest on the tops of the planks 29 and on the web 3() of the drawbar 26 and bottom plates 35 which are spaced from the top'plates 34 sufficient distance to permit insertion of the fillers 36 between the bottom plates 35 and the bottom of the planks 29 and flanges 27 of the -drawbar 26. Both the upper and lower plates 34 and 35, respectively, of' the bumper and the filler 36 extend inwardly to the rear edges of the end braces 18, the fillers 36 being cut away to receive the end braces 18. The upper and lower plates 34 and 35, respectively, are joined by an end plate 37 which is curved slightly to'conform to the curvature of the planks 29. The web 30 of the drawbar 26 is reenf'orced at its ends by plates 40 and also has secured thereto coupling members 42 which fit over the upper plates 34 of the bumpers 32 and have their outer ends spaced from the bumpers sufficiently to provide openings for the usual coupling links. The coupling members 42, the bumpers 32, the drawbar web 30 and iillers36 are provided with alined openings to receive the usual coupling pins 38.

At one end the body is closed by a swinging end gate 45 comprising a corrugated sheet47 pivotally mounted at 49 on the car sides 15 by means of the arms 48 and provided with an operating hookl 50 formed side of the sheet 47 and is bent upwardly at the center about an opening which is pro vided in the sheet 47.to receive a cou ling' member 42. At its other end the bo y is.

closed by a fixed corrugated end sheet having flanges 61 which overlap and are secured to the end'braces 18, and side sheets 15. The sheet 60 has a bottom flange 62 formed of an angle which rests upon and is secured to the planks 29 and side 4vfloor portions 14 of the car by bolts and rivets which engage the end brace 18.

The side floor portions 14 are provided with wheel openings 65 covered by wheel hoods 66 riveted to the lside floor portions by rivets 67 and secured to the side sills and journal boxes by bolts 68 and to the planks '29 and journal boxes by bolts 69. To the side sills 2 are secured brackets 70 in which arms 72 to which are pivotally connected brake bands 73 which have their other ends adjustably connected to brackets 74 mounted on the adjacent brace 18. At one end shaft 71 is provided with a crank arm 75 connected by a link 76 to a bell crank lever 77 pivotally mounted in a bracket 78 secured to the side floor portion of the car. The bell crank lever 77 is `connected by a link 8O -to an operating lever 81 pivotally mounted in a bracketv 82 connected to the fixed end sheet 60 of the car. The lever 82 is provided with a lug 84 which is adapted to engage in the teeth 85 formed in the guide bracket 86 mounted on the end sheet 60 to retain the brake lever in its adjusted position.
